Fuel Efficiency

As the Geneva Motor Show finally closes its doors to the public, many will go home lusting after the LaFerrari or McLaren's P1 hypercars. For others though, the show's indisputed star was the production Volkswagen XL1--as thoroughly engineered to be economical as the others are to be fast. While VW...

A few recent, high-profile cases have brought fuel economy testing procedure into question. When Kia and Hyundai are being sued for inaccuracies in reported EPA figures and Ford hybrid drivers are missing out on official numbers by 20 percent, suggesting the designs of some vehicles may enable them...

It's taken a while for carmakers to begin fitting stop/start systems to U.S. vehicles, such systems' benefits not really advertised to consumers in a car's EPA numbers. In the real world though, many manufacturers say the systems can save you significant amounts of fuel--particularly if you...

Kia has announced details of its updated Optima Hybrid, new for the 2013 model year. Just about every aspect of the car has been improved, resulting in a car that now offers greater fuel efficiency, improved space, better performance and a higher standard of equipment. Central to the changes are...

The Corporate Average Fuel Economy (CAFE) target of 54.5 mpg by 2025 has caused cheers from some people, and jeers from others. In reality, that target won't be as difficult to hit as the numbers suggest, as the average on EPA window stickers will be lower--closer to 40 mpg in reality. For some...

Following EPA head Lisa Jackson's resignation at the end of December, President Obama will nominate Gina McCarthy as her successor. McCarthy will become the Environmental Protection Agency's new administrator, following her role as head of the air and radiation office. A White House official has...

We've written quite a lot about the gas mileage of Ford's two new 2013 hybrid models, the C-Max and Fusion hybrids. That's because a lot of shoppers and buyers have been talking about it. Both cars are rated at 47 mpg combined, and neither car seems to achieve anything close to that rating in...

The 2013 Ford Fusion Hybrid is the second of Ford's two hybrid models, both all-new for 2013. The Fusion Hybrid, unlike the C-Max Hybrid compact hatchback, is a four-door mid-size sedan aimed right at the heart of a high-volume market segment. Competitors for the Fusion lineup include the Toyota...

Obviously, fuel economy will be an increasingly big deal in years to come. The gas-mileage ratings of new cars and trucks must double (and then some) between last year and 2025. But as two recent news events pointed out once again, EPA mileage ratings on the window stickers of new cars may not be...

Electric car-friendly Oregon may join the growing list of states imposing a dedicated tax on electric vehicles. Like other states looking to tax electric and fuel efficient cars, Oregon is pre-empting a rise in the number of electric vehicles on the roads and a subsequent fall in revenue from gas...

You probably started driving in a car with three, four, maybe five speeds to choose between. Manual transmissions led the way for a while with gears--five and six became commonplace, while the average auto might only have had four gears. Since then, an increasing quest for efficiency has seen that...

We hadn't driven a 2013 Nissan Sentra, the all-new compact sedan, until last week. And our drive was hardly representative, since we spent the bulk of it in the peculiar world of freeway traffic in Los Angeles. That means traffic moving at average speeds of anywhere from 60 to 85 mph, with...

The main benefits of Ford's Ecoboost line of engines may be fuel efficiency and performance, but their popularity is resulting in another positive outcome. Ford has sold more than 530,000 Ecoboost vehicles since the line's introduction three and a half years ago, and the automaker is ready to...

Last week, three members of High Gear Media's editorial staff sat down to discuss Mercedes-Benz, AMG, and their future technologies. The participants were editorial director Marty Padgett, social media manager Joel Feder, and senior editor Nelson Ireson--and they appeared in a Google+ 'Hangout on...

The choice of subcompact cars on the market has never been better. Not just better in terms of numbers either, but in quality, reliability, safety, equipment and every other factor the average buyer looks for in a car. Gas mileage isn't bad either, even if it doesn't match some of the paper-thin...

The quest toward better gas mileage and incremental gains isn't relegated just to engine and transmission improvements, or to aerodynamics or weight reduction. Even when we're not talking hybrids, the move to smart electric components can bring some significant gains. Beyond electric power...

To the average U.S. car buyer, the Volkswagen Up minicar will seem pretty basic. Deliberately designed to compete at the bottom of the European market, it always feels like a quality product--but always like a minimalist one too, with few of the bells and whistles found on most cars--unless you pay...

When a weather system dumps an uncommon amount of snow in your part of the world, thoughts often turn to how you might get about in it. Provided you've not got a seven-foot drift blocking you indoors, those plans might involve an all-wheel drive car. 4WD is no substitute for careful driving and a...

The Detroit Auto Show last month marked the debut of the a car with the lowest coefficient of drag of any production car--just 0.23. That car was the Mercedes-Benz CLA, a small sport sedan powered by a gasoline engine. Efficiency figures haven't yet been released, but we can imagine it being quite...

Back in November, we asked whether tinier, turbocharged engines were really the best way to get good gas mileage. Our assertion was that with the latest generation of small turbocharged engines replacing larger variants, the real-world gas mileage improvement is nowhere near that of the on-paper...
